Class XilinxVirtexIOB

java.lang.Object
  edu.byu.ece.edif.util.iob.AbstractIOB
      edu.byu.ece.edif.util.iob.XilinxIOB
          edu.byu.ece.edif.util.iob.XilinxVirtexIOB

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

XilinxVirtex4IOB

public class XilinxVirtexIOB
extends XilinxIOB

This class is currently written for Virtex devices only, though other architectures will probably work to some degree. Virtex-II and Virtex-II Pro work with this as far as we have been able to tell

XilinxVirtexIOB

public XilinxVirtexIOB(EdifSingleBitPort esbp)

Method Detail

setIBUF

public void setIBUF(EdifCellInstance ibuf,
                    EdifCellInstanceGraph graph)

iobComponentsDFS

private void iobComponentsDFS(EdifCellInstance ibuf,

setOBUF

public void setOBUF(EdifCellInstance obuf,
                    EdifCellInstanceGraph graph)

getAllInstances

public java.util.Collection<EdifCellInstance> getAllInstances()

Overrides:

getAllInstances in class AbstractIOB

canPack

public boolean canPack()

Description copied from class: XilinxIOB

Determines whether this XilinxVirtexIOB object corresponds to a clock IOB. This is done simply by checking the input buffer object. If the input buffer is an IBUFG*, then this is a clock IOB.

Overrides:

canPack in class XilinxIOB

Returns:

true if this XilinxVirtexIOB object corresponds to a clock IOB, false otherwise.

containsDDR

public boolean containsDDR()
